The equation in slope intercept form to represent the relationship is y = 12x + 15

An equation is an expression that shows the relationship between two or more numbers and variables.

The standard equation of a line is:

y = mx + b

Where m is the slope (rate of change) and b is the initial value of y.

Let y represent the total amount paid for renting a boat for x hours.

From the table, using the points (1, 27) and (3, 51):

The equation of the line is given as:

y - 27 = [(51 - 27)/(3 - 1)](x - 1)

y = 12x + 15

The equation in slope intercept form to represent the relationship is y = 12x + 15

In order for f(x) to be a linear function, determine the value of k in the data set.

x = {-7, -2, 2, 5}

f(x) = {-15, k, 3, 9}

The value of k is {-5}.

Given that to find the value of k in the data set such that the data set represents a linear function.

Linear Function is a straight line on the coordinate plane is represented by a linear function. The formula for a linear function is f(x) = mx + b, where m and b are real values.

Here, f(x) or y is the dependent variable, m is a slope of the line, x is the independent variable and b is the y-intercept.

Here,(x,f(x)) are {(-7,-15),(-2,k),(2,3),(5,9)}

The slope of the function,

(x, f(x)) = (2,3) and (5,9)

Slope formula is m=[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].

Slope m= [tex]\frac{9-3 }{5-2}[/tex]

Slope m=[tex]\frac{6}{3}[/tex]

Slope m=2.

Using the point slope form, determine the linear function's equation.

[tex]y-y_{1} =m(x-x_{1})[/tex]

Here, [tex](x_{1},y_{1})=(-7,-15)[/tex] and m=2

We get

y + 15 = 2 (x + 7)

y = 2x - 1

Now at x = -2 and f(x) = k

k = 2(-2) - 1

k = -4-1

k=-5

Therefore, the value of k is -5.

The probability that the inspector finds exactly one nonconforming part is 0.4091.

Combination is a selection of items from a collection in which the order of selection is irrelevant. Probability is defined as the ratio of favorable outcomes to total outcomes.

Now, according to the question;

Let X represent the event in which the inspector discovers a nonconforming part.

An inspector selects three parts at random from among the twelve, and two cavities have been affected by a temperature malfunction, resulting in parts that do not meet specifications.

The total number of ways to select three parts from a total of twelve is ¹²C₃ = 220.

The number of possible ways for an inspector to identify just one defective part is:

²C₁×¹⁰C₂ = 2×45

²C₁×¹⁰C₂ = 90

The likelihood that the inspector will discover exactly one nonconforming part is provided by:

P (x=1) = (²C₁×¹⁰C₂)/¹²C₃

          = 99/220

P (x=1) = 0.4091

The inspector has a 0.4091 chance of finding exactly one nonconforming part.

Now, the probability that inspector finds no nonconforming parts is given by:

P (x=0) = ¹⁰C₃×¹²C₃

           = 120/220

P (x=0) = 0.5455

Therefore, the inspector has a 0.5455 chance of finding exactly none nonconforming part.

Answer:to answer this question you have to look at what the relationship is between tones of sugar and the equation C(n) = 6,500 + 225n. The question gave you a hint in parenthesis in the form of (n) tons. This statement means that the amount of sugar is n so for question 1 the 13 tons is the n value.

Q1:

C(13) = 6,500 + 225*13

C(13) = 6,500 + 2,925

C(13) = 9,425

so what does the 9,425 mean? This is the cost to transport 13 tons of sugar.

Q2:

so this part n is unknown and we are given the C(n) number.

11,450 = 6,500 + 225n

subtract the 6500 from both sides

11,450 - 6,500 = 225n

evaluate

4,950 = 225n

I don't like the n on the right side so I am going to rewrite the equation

225n = 4,950

divide by 225

n = 4,950/225

evaluate

n = 22

So this result means that the company would transport 22 tones of sugar.

Have a great day!

The height of the drawing is 4 inches.

A scale drawing is a reduced form in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension

Scale of the drawing = original dimensions / dimensions of the scale drawing

The first step is to determine the scale of the drawing : 3000 / 10 = 300 feet : 1 inch

The second step is to determine the height of the drawing in the map: 1200 / 300 = 4 inches

Step-by-step explanation:

Given the question:

Play 1: Quarterback was sacked for a loss of 4 yards

Play 2 : Another loss of 10 yards

Play 3: a gain of 12 yards

Write an addition expression to represent the situation. Then find the sum and explain its meaning.

A loss of 4 yards = - 4

Loss of 10 yards = - 10

Gain of 12 yards = + 12

Addition expression for the scenario :

(-4) + (-10) + 12

Result :

-4 + (-10) + 12

= - 4 - 10 + 12

= - 14 + 12

= - 2

Hence, after two consecutive losses of 4 and 10 yards, the team wins 12 yards on the third play and the aggregate yards lost is reduced to 2 yards.

For a standard television of width 15 inches the correct options are

A. h/15=3/4, D) 15/h=4/3 and F) 4/15=3/h​.

Ratio is comparison between two or more quantities in simplest form.

The ratio of screen has a width to height ratio of 4:3.

We know a:b can be written as a/b.

∴ width:height = 4:3 can be written as (width/height) = (4/3).

So, Width = (4/3)height or Height = (3/4)width.

Given the height of a standard television is 15 inches.

So, 15 = (4/3)h or  h/15=3/4 or  15/h=4/3 or 4/15=3/h​.
